If your REST request is invalid, non "200" http responses can be returned:
400: "Invalid Request" - depending on the request details provided, further information on why the REST request is invalid may be stored in the log files which Savvy can provide if required.
Assuming your REST request is successfully received by our system, our API provides one level of error code which you need to handle:
Response Code (ResponseCode): These codes may indicate either a total failure, or a ‘partial success’, e.g. where the transaction proceeded, but for a lesser or greater amount than originally requested due to a transaction amount limit.
Please see the separate section on Response codes / Error Codes for further details
